I also have some trouble tipping and my foot moved around in my boot a bit. Even when my skis are close together I can't tip continually though the turn with only my foot. I have to force my knee out to get more tip.
The season is almost over but you are always welcome to work with Lorie and I. I have new video equipment for MA and take nice video of you skiing. Both Lorie and I have been working on improving our Superphantom turn. One of Lories work from this year was on this movement.
